Put your students’ engineering abilities to the test with this fun science fair project! They’ll explore why arches are such a common shape used for construction.
Germ experiments are among the most sought-after seventh grade science fair ideas. Swab objects to explore what’s living there.
Sporty kids will love this fun project that investigates how much electrolytes are in various sports drinks and demonstrates how to construct a catapult.
1. Build a Geodesic Dome
A geodesic dome is an impressive structure that showcases tension and compression, perfect for supporting structures and mechanisms sections in provincial and state science curricula. This project serves as a great educational experience.
This project is ideal for Grade 8 students. Students utilize a simple setup to demonstrate how liquids can be layered without mixing, which will definitely impress judges at a science fair! Please note: this project does require adult supervision.
2. Test the Cleaning Power of Laundry Detergent
Commercials for laundry detergent often feature lab technicians slapping mud or wine over clothing to demonstrate stain removal products’ efficacy, so this hands-on science fair project allows students to put these claims to the test and prove them for themselves.
Laundry detergent manufacturers must strike a delicate balance between stain-fighting efficacy and dye-friendly formulations in their formulas, and color preservation. A spectrophotometer can help manufacturers optimize their formulas.
3. Build a Model Roller Coaster
Investigating the physics of roller coasters can be exciting! Through Science Buddies’ project, students can discover how a roller coaster converts potential energy to kinetic energy.
Students can create their own model using foam pipe insulation, tape and a cup. Once completed, students can test out their designs by sending a marble down the track – watch closely as its energy fades at various points along its path!
4. Test the Temperature of the Atmosphere in a Jar
Adjusting air pressure with this simple experiment can show students how clouds form.
Layer liquids without them mixing using this classic science fair project and build a density tower that lights up! Bonus points if it glows!
Give your fifth graders an exciting engineering challenge by giving them clothespins and wooden craft sticks as creative engineering materials. Have them construct an airplane out of these materials that actually flies!
5. Build a Paper Cup Structure
Science fair projects should spark curiosity. To get ideas, look around your school or neighborhood – what stands out and makes you wonder?
If you’re in search of an easy STEM project with minimal materials required, try the Paper Cup Challenge. As iterative designs emerge from this project, try expanding upon it further!
6. Change the Color of Fire
Science fair projects provide high school students with a great way to explore their interests and develop critical thinking skills, yet how can you come up with something memorable?
Explore these awesome science fair projects that are sure to impress! These experiments range from creating a lava lamp and uncovering how DNA classification occurs to creating your very own lava lamp!
7. Test the Cleaning Power of Sports Drinks
Engineer-to-be will enjoy working on this 7th grade science fair project using simple household supplies. They’ll explore center of gravity and see how objects balance under various circumstances.
Steve Spangler Science offers this awesome density experiment for children curious about science. You can even tweak it to compare various types of sports drinks!
8. Build a Naked Egg
Engineering-minded students may enjoy this thrilling science fair project that challenges them to create a device capable of catching an egg dropped from a certain height without it breaking. Before beginning, administer the three-question Novice Engineer Pre-Assessment in order to help students think through solutions and evaluate how materials dissipate kinetic energy.
Watch metal particles dance and move in this amazing demonstration involving magnets and a clear plastic bottle!
9. Test the Relationship Between Ice and Salt
An opportunity for kids to investigate something they find intriguing while also learning more about scientific processes – formulating hypotheses and testing them – a science fair project provides.
Be a good example and demonstrate this concept by having students compare the melting times of two ice cubes–one made of water and one with salt added. Their results should be clear!
10. Build a Naked Egg in Vinegar
This experiment uses vinegar containing acetic acid, which reacts with calcium carbonate to form an acid that breaks down eggshells. Once this occurs, a completely naked egg remains that can be bounced or squeezed for fun!
Experiment by dropping an egg in various liquids such as water, syrup or salt water and watch its transformation over time. This exciting experiment not only provides entertainment but also serves to teach young people about chemistry!
